Abstract
The invention discloses an alcohol-free fountain solution. The alcohol-free fountain solution is prepared from the following substances of, in percentage by mass, 20%-35% of water, 0.5%-3% of sodium hydroxide, 1%-3% of sodium nitrate, 1%-3% of sodium citrate, 1%-3% of sorbitol, 0.1%-0.5% of a preservative, 28%-45% of ethylene glycol mono-tert-butyl ether, 1%-4% of a surfactant, 0.1%-2% of a defoaming agent, 0.5%-3% of citric acid monohydrate, 8%-15% of glycerin and 8%-12% of an anti-freezing solution. The alcohol-free fountain solution has the beneficial effects that the alcohol-free fountain solution is simple in material, low in VOC emission, low in soluble element content, small in environmental pollution, green, low-carbon, environmentally friendly and cost-saving, and can replace an alcohol fountain solution widely used in the market.
